Invention Patent Descriptive Report for SYSTEM AND METHOD OF MONITORING HAND HYGIENIZATION PRACTICES IN A HOSPITAL ENVIRONMENT AND A DEVICE WEARABLE BY A USER IN A HOSPITAL ENVIRONMENT.

[001] The present invention relates to a system and a method of monitoring hand hygiene practices in a hospital environment. More specifically, the present invention relates to a system and method capable of generating a virtual environment on a user-wearable device. The invention also proposes a device wearable by a user in a hospital environment. The teachings of the present invention can also be applied to the training of hand hygiene practices in a hospital environment.

Description of the state of the art [002] Hand hygiene is one of the most important procedures for the prevention of nosocomial infections. Dispensers (dispensers) comprising, in most cases, alcohol-gel, are disposed in different points of a hospital so that patients, visitors, collaborators and health professionals have the possibility to carry out the cleaning several times throughout the day.

[003] Thus, there is a constant investment and development of new methods and systems for monitoring hygiene practices in hospital environments. Additionally, and following technological advances, more and more equipment and accessories are used to support the systems used.

[004] Among the systems known in the state of the art, the system addressed in US 2004/0090333 is cited. In this case, a plurality of sensors (radiofrequency (RF) or infrared) are arranged within a hospital bed and are intended to

Petition 870170025728, of 04/19/2017, p. 7/67

2/35 monitor the movement of a specific doctor.

[005] Such a negative point is the fact that it is totally dependent on the use of an identification badge by the medical professional. That is, in US 2004/0090333 the doctor's identification badge communicates with sensors arranged in different environments (equipment, taps, among others), so that, if the doctor is not using his badge, the system will not operate.

[006] Some systems known in the state of the art are configured in order to issue an alert to the doctor indicating that he must perform a hygiene action. However, these alerts are mostly configured as lights or vibrating alerts that do not effectively attract the doctor's attention.

[007] That is, such alerts are not enough to motivate the doctor to perform a hand hygiene action, so that often the medical professional does not even realize that the luminous or vibrating alert has been carried out.

[008] Additionally, the state of the art reveals systems that make use of certain accessories that help the doctor to maintain compliance with hand hygiene and also help to improve the interaction between doctor and patient.

[009] For example, the document US 2015/0287182 discloses the use of smart glasses capable of determining the realization of touches on a certain surface so that a graphic that represents a path of contamination can be generated. It is also mentioned that each doctor, visitor and hospital equipment will have an associated identification number.

[0010] The focus of the teachings of US 2015/0287182 lies effectively in the generation of the so-called contamination path, so that this document does not specifically address means of

Petition 870170025728, of 04/19/2017, p. 8/67

3/35 monitor and encourage hygiene practices, the focus of the present invention.

[0011] The state of the art also reveals systems that use smart glasses to enhance the interaction between doctor and patient in a medical consultation, for example, providing information about the patient and providing a visible checklist to the doctor. Such characteristics, although interesting for the medical area, do not enhance hand hygiene practices and consequently do not help in order to reduce the occurrence of contamination.

[0012] Thus, it is known that the use of so-called smart glasses in the medical field is evolving, but so far there is no knowledge of a system that makes use of this type of accessory and that effectively helps in monitoring and encouraging practices hygiene.

[0013] The present invention aims to overcome existing problems in the state of the art and proposes a system and method for monitoring hand hygiene practices in a hospital environment.

[0014] The present invention overcomes the problems related to badge dependence through the use of infrared sensors (infrared cameras) that detect the heat emitted by a person and consequently can track the displacement of that person in a hospital environment.

[0015] Additionally, and in conjunction with the infrared sensors, the system proposed in the present invention also uses contact sensors and motion sensors in order to detect respectively touches performed by the medical professional on a given surface as well as the manipulation of potential devices causing infections, such as catheters.

Petition 870170025728, of 04/19/2017, p. 9/67

4/35 [0016] Thus, all movement and actions performed by a doctor within a hospital environment will be monitored by the system proposed in the present invention.

[0017] In order to effectively alert the medical professional regarding compliance with hand hygiene practices, the system makes use of a device that is wearable by the user and that is capable of reproducing a virtual environment, in which such a virtual environment reproduces a plurality of indicators related to hand hygiene compliance.

[0018] Among such indicators, the present invention reveals an indicator related to the virtual representation of an infectious agent, in which such virtual representation is exposed directly in the doctor's field of vision. Thus, if the doctor is not in compliance with hygiene practices, a virtual representation of a bacterium will be indicated to the doctor and he will be motivated to clean his hands. It is noteworthy that referring to a doctor should not be considered as a limitation of the present invention, obviously, the teachings of the invention can be applied to nurses, physiotherapists or any health professional.

[0019] Unlike the vibrational and light (green / red) indications known in the state of the art and which barely attract the doctor's attention, the virtual representation of a bacterium gives the doctor (health professional) the idea that a contamination is occurring thus consolidating, he is immediately motivated to perform hand hygiene.

[0020] Thus, and through the use of a set of sensors and a wearable device by the user, the present invention proposes a system and a method for monitoring hand hygiene practices in a hospital environment that overcomes known problems in the state of the technique.

Petition 870170025728, of 04/19/2017, p. 10/67

5/35 [0021] Finally, it is highlighted that the teachings of the present invention can be applied together with the material revealed in the requests BR 10 2016 027362-5 and BR 10 2014 027568-1, of these same depositors.

Detailed description of the figures [0037] A preferred representation of the system for monitoring hand hygiene practices in a hospital environment 1 (also referred to as system 1) will be described together with the representation of figures 1 to 10.

[0038] It is emphasized initially that in this preferential representation of system 1 the hospital environment should preferably be understood as a room in a hospital. In any case, it should be noted that this description should not be considered as a limiting feature of the present invention, so that the teachings proposed here are also applied to other hospital environments.

Petition 870170025728, of 04/19/2017, p. 15/67

10/35 [0039] By way of example, the referred hospital environment can be considered not only as a hospital room, but also as any internal area of the hospital (corridors, bathrooms, waiting rooms, surgical centers, among others).

[0040] Still, the reference to a hospital also represents only a preferential feature of the present invention, so that the teachings proposed here are also applicable to other health units, such as treatment units, follow-up units, rest units and units emergency that a given patient can accommodate, either for long or short periods of time.

[0041] In a generic way, the reference to a hospital environment should be understood as any place able to receive a patient. [0042] With specific reference to figures 1 to 3 and 8 to 10, the system 1 proposed in the present invention comprises a set of sensors 2, 3, 4 and 5 arranged inside the hospital environment.

[0043] Preferably, system 1 comprises a plurality of infrared sensors 2 arranged in the hospital environment, each of these sensors establishing a heat detection zone 20.

[0044] Such infrared sensors 2 are configured in order to detect the heat emitted by people or equipment (pumps, monitors, televisions, among others) disposed inside the hospital environment. Said sensors 2, preferably configured as an infrared camera, generate an image pattern, such as a heat map, which allows to identify the movement of a person within the environment, as well as if he is lying in the bed of the hospital room.

[0045] Preferably, infrared sensors 2 should be arranged on the ceiling of the hospital environment and so that all

Petition 870170025728, of 04/19/2017, p. 16/67

11/35 the area of the environment is captured by the heat detection zone 20 of each of the sensors 2. Alternatively, the arrangement of the sensors on the walls of the hospital environment is fully acceptable.

[0046] The heat detection zone 20 must be understood as the detection area of the infrared sensor 2, that is, the area where the sensor 2 is able to detect the heat emitted by a certain person or equipment.

[0047] Said heat detection zone 20 can be calibrated according to the infrared sensor 2 used, in addition, the way in which heat detection zone 20 is illustrated in figures 1 and 3 should not be considered as a limitation of the present invention.

[0048] The use of infrared sensors 2 provides advantages for tracking a certain person or equipment within the hospital environment, for example, using such sensors (infrared cameras), it is possible to track an individual even if he is not using an identification badge. identification equipped with a radio frequency sensor (RF sensor).

[0049] For example, it is known that some systems proposed in the state of the art present the so-called dependency badge, that is, such systems will only operate properly if the person (doctor, visitors, nurses, physiotherapists or any professional in the field) health) using an identification badge, otherwise tracking will not be possible and the system will operate improperly.

[0050] Similarly, the state of the art reveals systems in which identification tags (equipped with radio frequency sensors) are placed on equipment, in order to assess when such equipment has been touched. As mentioned above, if such labels are not present on the equipment and the doctor is not present, Petition 870170025728, of 19/04/2017, p. 17/67

12/35 already using your identification badge, it will not be possible to detect when these have been touched.

[0051] Such inconveniences do not occur with the proposed system 1, since the tracking is obtained from the heat emitted by the human body or by a certain equipment, so it is possible to perform the tracking even if the person and the equipment are not using the badge and identification tag.

[0052] Preferably, the infrared sensors 2 used in the system proposed in the present invention have the characteristics of the infrared sensors described in patent application BR 10 2014 027568-1, of these same depositors, and the description of which is incorporated herein by reference.

[0053] In addition to the infrared sensors 2, the system 1 proposed in the present invention also comprises a motion sensor 4 associated with an article 10 of the hospital environment, as shown in figures 3, 8 and 9. Only preferably, and without causing any limitation to the scope of protection of the present invention, motion sensor 4 should be understood as the set of an accelerometer and gyroscope.

[0054] Specifically, the motion sensor 4 must be disposed in an invasive device, such as a catheter, so that it is possible to determine the moment when the said invasive device was manipulated by a medical professional.

[0055] The reference to a catheter should not be understood as a limiting feature of the present invention, in general, the motion sensor 4 can be disposed in any invasive device, that is, in a central catheter, a bladder probe, a tracheostomy, an orotracheal tube, among others. It should be noted that the reference to an invasive device must be understood as any device that causes the rupture of natural barriers or penetration. Petition 870170025728, of 04/19/2017, p. 18/67

13/35 in cavities of the organism, allowing access to the internal environment of the cardiocirculatory system, the respiratory system, the urinary system, or any other system of the human body.

[0056] Preferably, the motion sensors 4 used in the system proposed in the present invention have the characteristics of the motion sensors described in patent application BR 10 2014 027568-1, of these same depositors, and the description of which is incorporated herein by reference .

[0057] In addition to the infrared sensors 2 and motion sensors 4 previously discussed, the system 1 proposed in the present invention also comprises a trigger sensor 5 of an aseptic dispenser 6, as illustrated in figures 7, 8, 9 and 10.

[0058] The aseptic substance dispenser 6 is preferably configured as an alcohol-gel dispenser, such equipment commonly disposed inside hospital rooms so that medical professionals, patients and visitors can perform hand hygiene. Obviously the reference to alcohol-gel should not be considered as a limitation of the invention, so that any antiseptic substance suitable to be disposed inside a dispenser could be used, for example, soap or chlorhexidine.

[0059] The drive sensor 5 must be understood as any sensor capable of detecting that a sanitizing action has occurred, that is, a sensor capable of detecting that the aseptic substance dispenser 6 has been used.

[0060] Preferably, the drive sensors 5 and the aseptic substance dispenser 6 used in the system proposed in the present invention have the characteristics of the sensors and dispensers described in patent application BR 10 2014 027568-1,

Petition 870170025728, of 04/19/2017, p. 19/67

14/35 of these same depositors, the description of which is incorporated herein by reference.

[0061] In addition to the infrared sensors 2, motion sensor 4 and drive sensor 5, the system 1 proposed in the present invention also makes use of a contact sensor 3 associated with at least one article 10 'disposed in the hospital environment, as preferably seen from figure 2.

[0062] The contact sensor 3 is preferably configured as a film with a plurality of sensors (capacitive or resistive) and which is associated with a surface of the article 10 '.

[0063] Such sensors are able to detect the occurrence of a touch on the surface of the article 10 'on which the contact sensor 3 is disposed. For example, and with reference to figures 2 and 3, the arrangement of the contact sensor 3 on a first surface 100 of an infusion pump allows to detect when the medical professional has touched the surface 100 of said pump.

[0064] It is emphasized that the description of article 10 'as an infusion pump should be considered only as a preferential feature of the present invention, in alternative modalities, the contact sensor 3 could be disposed in any other article 10' provided in hospital environment, such as monitors, furniture and decoration items, switches, taps, or any other equipment where you want to check for the occurrence of a contact.

[0065] Preferably, the contact sensors 3 used in the system proposed in the present invention have the characteristics of the contact sensors described in order BR 10 2016 027362-5, of these same depositors, and whose description is incorporated by reference.

[0066] The use of infrared sensors 2, contact sensors 3, motion sensor 4 and drive sensor 5 allows

Petition 870170025728, of 04/19/2017, p. 20/67

15/35 that the actions taken by a medical professional within the hospital environment are tracked and consequently their hand hygiene practices are evaluated.

[0067] For example, and due to the infrared sensors 2 it will be possible to track the movement of the medical professional inside the hospital environment, since the contact sensor 3 allows to evaluate whether a certain equipment has been touched and the movement sensor 4 allows to determine if manipulation of an invasive device occurred. [0068] As previously discussed, and from the use of infrared sensors 2 in conjunction with the other sensors in the system, the monitoring of hand hygiene practices is allowed even if the doctor / visitor is not wearing a health badge. identification (equipped with a radio frequency sensor, for example). In this case (badge is not used), it will be possible to monitor hygiene practices and possible violations of such practices, but it will not be possible to determine who is being monitored and who has violated such practices.

[0069] To identify the medical professional monitored by the system, he must be using an identification badge 70 equipped, for example, with a radio frequency sensor (as shown in figure 3). In addition, the other sensors in system 1 (infrared 2, contact 3, movement 4 and drive 5) must also have a radio frequency module associated with each of the sensors, so that communication with the radio badge sensor of the identification badge is thus possible.

[0070] The data detected by such sensors, as well as the combination of these, allow us to assess whether hand hygiene practices are in accordance with a standard previously established by a health institution.

[0071] For example, with system 1 proposed in the present inventionPetition 870170025728, of 19/04/2017, p. 21/67

16/35 tion, it is possible to assess whether hygiene practices are in accordance with the so-called Five Moments for Hand Hygiene, that is, the five moments when hand hygiene in a hospital environment should be performed.

[0072] The table below indicates what these five moments are and why the hand hygiene procedure should be performed:

Five Moments for Hand Hygiene Why? 1 - Before contact with the patient For the protection of the patient, avoiding the transmission of microorganisms present in the hands of the professional and that can cause infections. 2 - Before performing an aseptic procedure For the protection of the patient, preventing the transmission of microorganisms from the hands of the professional to the patient, including the microorganisms of the patient himself. 3 - After risk of exposure to body fluids For the protection of the professional and the care environment immediately close to the patient, preventing the transmission of microorganisms from the patient to other professionals or patients. 4 - After contact with the patient For the protection of the professional and the health care environment, including surfaces and objects close to the patient, preventing the transmission of microorganisms from the patient himself. 5 - After contact with areas close to the patient For the protection of the professional and the health care environment, including surfaces and objects immediately close to the patient, preventing the transmission of microorganisms from the patient to other professionals or patients.

[0073] To this end, and as will be better addressed below, the system 1 proposed in the present invention establishes a plurality of hygiene signs 11 and 11 ', in which such hygiene signs 11,

11 'are associated with a hand hygiene event.

Petition 870170025728, of 04/19/2017, p. 22/67

17/35 [0074] By hygiene event, it should be understood as an opportunity in which the medical professional had to hand hygiene and did not do it (considering a specific hygiene protocol of an institution) or a properly performed hygiene action .

[0075] For example, a hygienic opportunity can be considered as one of the five hygiene moments mentioned above in which the medical professional should have hygienized their hands.

[0076] Thus, and in general lines, the reference to a hygiene event in the present invention should be understood as a hygiene action already performed or a hygiene action that should have occurred, but did not occur (hygiene opportunity).

[0077] In this way, and associating the hygiene events with the hygiene signs 11 and 11 '', system 1 establishes a first hygiene sign 11 related to the act of having the hands cleaned, that is, whenever a cleaning action is performed. sanitation occurs (trigger sensor 5 has been triggered), a first sanitation signal 11 will be generated by system 1 proposed in the present invention.

[0078] Similarly, and from the information captured by the set of sensors 2, 3, 4 and 5, system 1 establishes a second hygiene signal 11 'related to a hand hygiene opportunity.

[0079] An important characteristic of the system 1 proposed in the present invention resides in the fact that the first and second signs of hygiene 11 and 11 'are indicated to the medical professional in a wearable device 15 thereof.

[0080] By wearable device 15, it is understood as any device that can be used by the medical professional and that is able to reproduce video, audio, image files, connect to the InPetition 870170025728, of 04/19/2017, page . 23/67

18/35 ternet, such as a watch or glasses. In this preferred modality of system 1, and in reference to figure 4, the wearable device 15 should preferably be understood as glasses used by the medical professional, a device that also provides protection to the user who wears it, acting as an Individual Protection Equipment (PPE). More specifically, said wearable device 15 should preferably be configured as smart glasses (smart glass), as well as the models already known: Google glass, HoloLens (Microsoft), and also the models of the companies Vuzix, Epson, Sony, among others. Obviously, the use of these models is a non-limiting feature of the present invention, alternatively, any other model of smart glasses could be used.

[0081] It is known that such devices are endowed with several functionalities and characteristics, such as the possibility of connection to the world wide web, use of video cameras to record the environment around the device, interaction screens, among others.

[0082] Thus, the present invention proposes the use of a set of sensors 2, 3, 4 and 5 together with the wearable device 15 in order to monitor and encourage hand hygiene practices in a hospital environment.

[0083] More specifically, and with reference to figure 4, the wearable device 15 is configured to generate a virtual environment 16 visible by the user (medical professional) of system 1, in which a plurality of indicators 25, 26, 27 and 28 related at the first and second hygiene signs 11 and 11 'are displayed in the virtual environment 16.

[0084] By virtual environment 16, it should be understood as the representation in augmented reality (augmented reality) in a determined area of the lens of the wearable device 15. The representation of the

Petition 870170025728, of 04/19/2017, p. 24/67

19/35 virtual environment 16 in augmented reality allows the medical professional or any health professional to continue performing their duties within the hospital environment, but still allows certain information to be provided to the professional through the plurality of indicators.

[0085] More specifically, and only preferentially, the plurality of indicators is configured as at least one among a video element 26 (figure 4 (a)), a text element 27 (figures 4 (b) and 4 ( c)) and a play element 28 (figure 4 (d)).

[0086] Each of these indicators aims to act as an alert to the medical professional about a hygiene action that occurred (first sign of hygiene 11) or about an opportunity for hand hygiene (second sign of hygiene 11 ') .

[0087] More specifically in relation to figure 4 (b), the representation by means of a text indicator 27 can, by way of example, alert the medical professional regarding a correctly performed hygiene action. Thus, the augmented reality representation of the text Congratulations can be indicated in the virtual environment 16.

[0088] Such representation can be indicated on the wearable device 15, since the infrared sensors 2 and the drive sensors 5 detected that a correct hygiene action was performed prior to the doctor's contact with the patient (first hygiene time) .

[0089] Similarly, and in reference to figure 4 (c), infrared sensors 2 and trigger sensors 5 can indicate that after contact with the patient, a hygiene action should have taken place but was not detected, ie , a hygienic opportunity occurred. Thus, the text indicator 27 related to a sePetition 870170025728, of 04/19/2017, p. 25/67

20/35 second sanitizing signal 11 'will be displayed in virtual environment 16, for example, with the indication of the fourth sanitation time violated !.

[0090] It should be noted that the fourth cleaning moment refers to a cleaning action that should occur after contact with the patient, as previously indicated.

[0091] The representation through the text element 27 can be replaced by the indication via a graphic element (image) 25, as seen from figures 5 (a) and 5 (b). Obviously, the text elements 27 and graphics 25 indicated in the figures in question are to be considered only as preferential representations of the present invention.

[0092] In addition to the use of graphic elements 25 and text 27, the system 1 of the present invention also allows the generation of the virtual environment 16 and the use of a playful element 28 related to the first 11 and the second 11 'hygiene signs.

[0093] With reference to figure 6, it is observed that in the system 1 proposed in the present invention the play element 28 is configured as a virtual representation of an infectious agent 30, that is, the play element 28 is configured as a virtual representation of a bacterium. Figure 6 (a) illustrates the virtual representation of the bacteria called staphylococcus (Staphylococcus) and figure 6 (b) illustrates the virtual representation of the bacterium called Enterobacteriaceae. [0094] In additional reference to figure 7, system 1 proposed in the present invention presents as an additional feature the fact that the virtual representation of the infectious agent 30 is a transient representation.

[0095] More specifically, the virtual representation of the infectious agent 30 is transient between a first state 31 and a second state 32, where the first state 31 is associated with the second signal

Petition 870170025728, of 04/19/2017, p. 26/67

21/35 of sanitization 11 '(sanitizing opportunity) and the second state 32 is associated with the first sanitizing sign 11 (sanitizing action occurred).

[0096] In other words, the virtual representation of the infectious agent 30 in its first state 31 is related to an opportunity for hand hygiene, whereas the virtual representation of the infectious agent 30 in its second state 32 is related to a properly sanitized action fulfilled.

[0097] Additionally, and still referring to figure 7, it is understood that in the first state 31 the virtual representation of the infectious agent 30 is visible to the user through the wearable device 15, in the second state 32, the virtual representation of the infectious agent 30 is not visible to the user through the virtual environment 16.

[0098] Thus, it is considered a medical professional 39 who enters a hospital environment, such as a hospital room, to perform a particular treatment on a patient 40. Infrared sensors 2 (not shown) in figure 7) detected a certain route data 35 from the medical professional 39 such as the route indicated by means of the dashed lines shown in figure 7.

[0099] It is observed that the route data 35 indicates that the medical professional's displacement was carried out directly to the patient's bed 40 and that consequently there was no triggering of the aseptic substance dispenser 6, that is, a hygienization opportunity occurred and the first hygiene moment (before contact with the patient) was violated.

[00100] In this scenario, the violation of the first cleaning moment will be indicated on the wearable device 15 through the virtual representation of an infectious agent 30 visible to the user via augmented reality. That is, the indication of the playful element 28 by means of

Petition 870170025728, of 04/19/2017, p. 27/67

22/35 an infectious agent 30 in the virtual environment 16 will be visible to the doctor

39.

[00101] Consequently, the medical professional 39 will be alerted that a hygiene action should have taken place, but it was not carried out and, through the indication of the infectious agent 30 directly in his field of vision (via augmented reality), the medical professional 39 will have awareness that not hand hygiene can cause infections to the patient, so the doctor 39 is motivated to perform hand hygiene and consequently reduce the chances of bacteria proliferation.

[00102] In this way, and directly motivated by the indication of the infectious agent 30, the medical professional will be motivated to go to the alcohol-gel dispenser 6 and consequently perform a hand hygiene action. In this way, a new route data 35 'will be detected by the infrared sensors 2 representing the displacement of the doctor 39 to the alcohol dispenser 6.

[00103] The activation of the dispenser 6 will be duly confirmed through the activation sensor 5, indicating that a hygiene action has taken place. In this way, and from the generation of the first hygiene sign 11, the virtual representation of the infectious agent 30 will reach its second state 32, that is, the state in which such representation is not visible to the medical professional 39.

[00104] Once the hygiene action has been carried out, an indicator can be provided in the virtual environment 16 related to the compliance of the hygiene action, for example, such as the text element 27, indicating via augmented reality the congratulations to the medical professional 39.

[00105] Thus, and through the use of the wearable device 15, there is an indication of easy perception to the user that a protocol

Petition 870170025728, of 04/19/2017, p. 28/67

23/35 hygiene has been violated, so that the representation in the virtual environment 16 directly in the doctor's field of vision 39 potentially reduces the chances that such an alert will simply be dismissed by the professional 39 and he will follow the medical procedures without the correct hygiene of the hands.

[00106] Furthermore, and using the set of sensors 2, 3, 4 and 5, it is possible to track not only the displacement of the doctor 39 as well as the manipulation of invasive devices and contact with certain surfaces.

[00107] Thus, and in reference to figure 8, a certain sequence of actions taken by a medical professional 39 in a given hospital environment is considered, in which said hospital environment comprises dispensers of aseptic substance 6, a first article 10 configured as a monitor, a second article 10 'configured as an infusion pump and a third article 10' 'configured as an invasive device, such as a catheter.

[00108] In order to detect possible touches made by the medical professional 39 on the monitor 10 and the infusion pump 10 ', these additionally comprise touch sensors 3 arranged on one of its surfaces, additionally, and aiming to detect the manipulation of the catheter 10 ” physician 39, this comprises a motion sensor 4 associated with said catheter 10 ''.

[00109] The hygiene protocol for the hospital environment represented in figure 8 is considered to be the following: hands should be cleaned immediately upon entering the environment, immediately after contact with any surface or equipment and immediately after contact with the patient. [00110] It is also considered a certain route taken by the medical professional 39, as well as the path indicated by the route data 35 represented in figure 8. It is observed that the medical professional 39 cleaned his hands immediately after entering the amPetition 870170025728, of 04/19/2017, p. 29/67

24/35 hospital environment and then went to monitor 10, for example, to assess the patient's medication history 40.

[00111] Then, the doctor 39 went to the 10 'infusion pump to assess the dosage of intravenous medication that will be administered to the patient and subsequently manipulated the 10' 'catheter for its proper positioning and connection to the patient's blood flow

40. Subsequently, doctor 39 went directly to the exit from the hospital environment.

[00112] As a representation of figure 8, it is observed that during this displacement the medical professional 39 cleaned his hands immediately after entering the hospital environment. That is, it is noted that the doctor 39 did not clean his hands after having contact with the monitor 10, with the infusion pump 10 'and after the contact and manipulation of the invasive device 10' ', actions that represent potential actions of bacteria proliferation and contamination.

[00113] With the system 1 proposed in the present invention, such non-conformity in the hygiene practices would be properly detected by the infrared sensors 2, contact sensors 3 and motion sensor 4 that respectively would determine route data 35 of the medical professional 39, data of contact 36 of the doctor 39 with the monitor 10 and infusion pump 10 '(articles) of the hospital environment and movement data 37 of the catheter (article) used to administer medication to the patient.

[00114] Thus, the medical professional 39 who makes use of the wearable device 15 in accordance with the teachings of the present invention will be immediately alerted to the hygiene non-conformities detected after contact with the monitor 10, infusion pump 10 'and manipulation invasive device (catheter 10 '').

[00115] In this sense, figure 8 further illustrates possible representations of the virtual environment 16 considering the path taken by the

Petition 870170025728, of 04/19/2017, p. 30/67

25/35 doctor 39. It is noted that after carrying out the cleaning in the dispenser (doser) 6, the virtual environment 16 indicates by means of a text element a message of compliance with the hygiene standards (t1).

[00116] However, after the touch on the monitor 10 and the infusion pump 10 'has been detected and the dispenser 6 has not been activated, indicators of non-compliance with hand hygiene practices are respectively provided to the doctor 39 ( t2 and t3).

[00117] Similarly, an indicator of non-conformity, such as by means of the representation of a playful element 28, is visualized in the virtual environment 16 since the manipulation of the catheter 10 '' was verified and an action of hygiene (t4) before doctor 39 leaves the hospital.

[00118] Thus, system 1 proposed in the present invention allows the monitoring of hand hygiene practices considering the displacement performed by a medical professional, as well as their contact with certain equipment and the manipulation of invasive devices, such as catheters .

[00119] In order to evaluate the hygiene practices of the hospital environment, a history of indicators provided to the wearable device 15 should be sent to a central control of the hospital environment. Similarly, route data 35, contact data 36, movement data 37, drive data 38 and first 11 and second 11 'sanitation signals must also be sent to a hospital control center, thus allowing management to assess the hygiene history of the entire hospital environment.

[00120] The teachings of the present invention can also be applied in training practices of medical professionals in hospital environments.

Petition 870170025728, of 04/19/2017, p. 31/67

26/35 [00121] For example, medical professional 39 who performed the actions shown in figure 8 is considered a resident physician in training, thus, it was evidenced that he violated some hygiene practices considering the institution's protocol. It is understood that the reference to a resident doctor represents only a preferential feature of the invention, so that the teachings proposed here can be applied to any health professional.

[00122] In order to inform the doctor 39 about the result of the training carried out, a conformity index 45 (for example, on a percentage scale) could be displayed in the virtual environment 16 of the wearable device 15 at the moment the doctor leaves the hospital environment (t = 5). Considering the example in figure 8, the compliance rate 45 of doctor 39 would be low, since several hygiene protocols were violated.

[00123] More specifically, the compliance index 45 can represent an adherence rate related to hand hygiene practices, so that such adherence rate can be obtained by dividing the number of times that the hygiene occurred by the total of hygiene opportunities, the result of this division, multiplied by 100, can represent the adherence rate.

[00124] It is noteworthy that such way of obtaining the conformity index 45 represents only a preferential characteristic of the present invention, so that in alternative modalities, the conformity index 45 could be represented using one among the indicators 25, 26, 27 and 28 already mentioned or dividing the number of hygiene opportunities by the number of sanitizations actually performed.

[00125] In this sense, figure 9 illustrates the displacement and actions performed by a specific medical professional 39 in an environment 870170025728, of 04/19/2017, p. 32/67

27/35 te hospital as well as representations of the virtual environment 16 displayed on the wearable device 15 according to the movement and actions performed.

[00126] It is observed that the doctor 39 cleaned his hands as soon as he entered the hospital environment (t1) and subsequently had contact with the monitor 10. Then, and in compliance with the hygiene protocols, a new hygiene action is observed after contact with monitor 10 and before contact with the infusion pump 10 '(t3). Considering the teachings of the present invention, the cleaning action performed before contact with the 10 'infusion pump was motivated by the indication of the text element Clean hands after the doctor 39's contact with monitor 10 (t2).

[00127] After contact with the 10 'infusion pump and before handling the 10' 'catheter, the doctor 39 cleaned his hands again, motivated by the virtual representation of the infectious agent 30 (t4). Finally, a new hygiene action is observed before the doctor 39 leaves the hospital environment.

[00128] In this representation of figure 9, it is observed that the hygiene protocols were duly followed, thus, in the event that such displacement represents the training of a medical professional 39, the compliance index 45 would reach its maximum score, as illustrated in figure 10 (t6).

[00129] In the example commented on based on figure 9, the compliance index 45, also referred to as an adherence rate, would reach its maximum value (100%), this because the opportunities for hand hygiene considering the institution's hygiene protocol were as follows: A first hygienic opportunity when entering the hospital environment, a second hygienic opportunity after contact with monitor 10, a third hygienic opportunity after contact with the 10 'infusion pump and a

Petition 870170025728, of 04/19/2017, p. 33/67

28/35 fourth hygienic opportunity after contact with the invasive device and contact with the patient.

[00130] Thus, a total of four hygiene opportunities were detected and, considering the route data 35 represented by figure 9, there is a total of four hand hygiene actions. In this way, the compliance index 45 (adherence rate) would be obtained by dividing the total hygiene actions actually performed (4 actions performed) by the total hygiene opportunities (4 opportunities), multiplying by 100, one 100% compliance index would be obtained.

[00131] Regarding the medical professional's route data 35, as shown in figure 8, the same amount of hand hygiene opportunities can be seen when compared to the representation in figure 9, that is: A first hygiene opportunity when enter the hospital environment, a second cleaning opportunity after contact with the monitor 10, a third cleaning opportunity after contact with the infusion pump 10 'and a fourth cleaning opportunity after contact with the invasive device and the patient.

[00132] However, considering the route data 35 illustrated in figure 8, there is only one hygiene action actually performed (just after the medical professional 39 enters the hospital environment). Thus, dividing the total hygiene actions actually performed (1 action performed) by the total hygiene opportunities (4 opportunities), and multiplying the value by 100, a compliance index 45 (adherence rate) of 25 % would be obtained.

[00133] It should be noted that in reference to the representation of the figures and 9 the hygiene protocol used by the hospital environment in question is as follows: You should clean your hands as soon as you enter the

Petition 870170025728, of 04/19/2017, p. 34/67

29/35 environment, right after contact with any surface or equipment and right after contact with the patient. Obviously, such a hygiene protocol should not be considered as a limiting feature of the present invention.

[00134] Thus, it is understood that the compliance index 45 represents an adherence rate related to the hygiene practices of a given hospital environment, more specifically, the compliance index 45 is related to a hygiene action actually performed (first sign hygiene 11) and an opportunity for hand hygiene (second sign of hygiene 11 ').

[00135] It should be noted that in the case of using the teachings of the present invention for training medical professionals, it is advisable to indicate in the virtual environment 16 only the compliance index 45 after the doctor leaves the hospital environment. That is, any representations of indicators 25, 26, 27 and 28 that may alert the doctor to hygiene practices violated during training (such as the representations in t2, t3 and t4 in figure 8) may not be displayed to the user. Obviously, it will be up to the instructor 50 of the training to determine which of indicators 26, 27, 28 and 45 should be displayed to medical professionals during their training.

[00136] The system 1 proposed in the present invention can be applied to different environments in a hospital (hospital environment) in order to monitor, motivate and train professionals in relation to hygiene practices performed within the hospital. If system 1 is used for training medical professionals, a single instructor 50 can coordinate the training of multiple professionals 39, 39 ', 39' 'and 39' '' using the wearable device 15, as illustrated in figure 10.

Petition 870170025728, of 04/19/2017, p. 35/67

30/35 [00137] In this case, the instructor 50 can receive on his personal computer images captured from each of the wearable devices 15 used by doctors 39, 39 ', 39' 'and 39' ''. Additionally, instructor 50 can determine the sending of indicators 25, 26, 27, 28 and 45 to the virtual environment 16 of the devices 15 used by doctors 39, 39 ', 39' 'and 39' '' depending on the actions performed by them in their training.

[00138] Obviously the reference to a personal computer of the instructor 50 should be considered as a only preferential description of the present invention, alternatively, any electronic component capable of receiving images and videos (such as a tablet, cell phone or even the wearable device 15 ) could be used.

[00139] Alternatively, each of the doctors in training 39, 39 ', 39' 'and 39' '' can also communicate with the instructor 50, for example, to resolve any doubts that arise during the training. Such communication can take place through a communication system, such as a Wi-Fi network in the hospital environment. Obviously other forms of communication are acceptable.

[00140] Furthermore, the system 1 proposed in the present invention allows the instructor 50 to send to each of the wearable devices 15 of the doctors 39, 39 ', 39' 'and 39' '' a video element indicator 26, such as the representation of figure 4 (a). In this video, instructor 50 can inform doctors 39, 39 ', 39' 'and 39' '' which hygiene protocols are considered ideal and should be performed during training. Thus, the indicator in video element 26 can operate as a tutorial for doctors in training.

[00141] If the teachings of the invention are applied to practical and real-time monitoring of hygiene actions in a hospital environment, it is advisable to represent the virtual environment 16 and indicators 25, 26, 27 and 28 as soon as an action of

Petition 870170025728, of 04/19/2017, p. 36/67

31/35 hygiene is correctly performed or as soon as an opportunity for hand hygiene has occurred, in this way, system 1 motivates medical professionals 39 to always comply with hygiene practices in the hospital environment.

[00142] In this case, the compliance index 45 can be used as a hygiene history 46 of the hygiene practices of a given doctor after a period predetermined by the hospital organization, that is, a history related to the adherence rate for hand hygiene of a particular medical professional. For example, you can use the compliance index 45 (adherence rate) to represent the physician's hygiene compliance after performing a surgical procedure, or after a day or month of work. Said hygiene history 46 can be sent to the hospital organization and configured as a conformity report, as preferably illustrated in figure 11. [00143] In harmony with the system for monitoring hand hygiene practices in a hospital environment, the The present invention also addresses a method of monitoring hand hygiene practices in a hospital environment, also referred to only as a monitoring method.

[00144] Figure 12 illustrates a block representation of the monitoring method proposed in the present invention. In harmony with the system 1 already described, the method comprises the step of generating a plurality of sanitation signals 11, 11 'from data obtained from the set of sensors 2, 3, 4, 5.

[00145] Preferably, the set of sensors is configured as at least one between an infrared sensor 2, a contact sensor 3 of an article disposed in the hospital environment, a motion sensor 4 of an article disposed in the hospital environment and a trigger sensor 5 of an aseptic dispenser.

Petition 870170025728, of 04/19/2017, p. 37/67

32/35 [00146] In harmony with system 1 previously described, and in reference to figure 12, the monitoring method also comprises the step of generating a virtual environment 16 on a wearable device 15 by a user, in which the virtual environment 16 is visible by the user. The method also comprises the step of displaying a plurality of indicators 25, 26, 27, 28, 45 in the virtual environment 16, in which the plurality of indicators 25, 26, 27, 28, 45 are related to hygiene signs 11, 11 '.

[00147] With reference to figures 4, 6, 7, 8, 9 and 12, the monitoring method also comprises the step of generating a virtual representation of an infectious agent 30 in the virtual environment 16, the virtual representation of the infectious agent 30 configured as a transient representation between a first state 31 and a second state 32, where in the first state 31 the virtual representation of the infectious agent 30 is visible to the user and in the second state 32 the virtual representation of the infectious agent 30 is not visible to the user.

[00148] Additionally, the method further comprises the step of activating the trigger sensor 5 of an aseptic substance dispenser 6 so that the virtual representation of an infectious agent 30 passes from the first state 31 to the second state 32.

[00149] In harmony with the previously described system 1, the proposed monitoring method still comprises the steps of generating a first hygiene signal 11 from the activation of the trigger sensor 5 of an aseptic dispenser 6 and generating a second signal hygienic cleaning 11 'from at least one of the following data obtained from the sensor set 2, 3, 4, 5: a user path data 35 obtained from the heat detection zones 20 of the infrared sensors 2, a contact data 36 of the user with an article 10 of the hospital environment, the contact data 36 obtained from the contact sensor 3, a movement data 870170025728, of 19/04/2017, p. 38/67

33/35 ment 37 of article 10 of the hospital environment, the movement data 37 obtained from the motion sensor 4, and an activation data 38 of the aseptic substance dispenser 6.

[00150] Thus, the present invention relates to a method and a system for monitoring hand hygiene practices in a hospital environment and which made use of a plurality of sensors to monitor the actions performed by a medical professional 39 within the hospital environment.

[00151] From the teachings of the present invention, it is possible, for example, to track the movement of a medical professional 39, as well as to determine if he has touched surfaces that may be contaminated or to increase the occurrence of contamination. In addition, it can be determined whether the manipulation of an invasive device has occurred.

[00152] Additionally, the representation of the virtual environment 16 in the wearable device 15 allows an indication directly in the doctor's field of view to be carried out, motivating such professional to stay within the hygiene protocols.

[00153] Furthermore, the virtual representation of the infectious agent 30 through the play element 28, in addition to informing the medical professional 39 about a violation in the hygiene protocols, motivates him to immediately perform a hygiene action, since the representation of the bacterium the doctor gives the idea that the occurrence of an infection is evident, thus, the representation of such an infectious agent ends up motivating the medical professional to immediately perform a hygiene action.

[00154] Finally, it is understood that the description of some elements and characteristics of the system and method proposed in the present invention should not be considered as limiting characteristics of the invention.

Petition 870170025728, of 04/19/2017, p. 39/67

34/35 [00155] For example, the reference to a hygiene protocol such as the already known five hygiene moments should not be considered as a limiting aspect of the invention, so that any hospital environment that makes use of the teachings of the present invention be able to define the hygiene protocol that best fits the hygiene practices of the hospital.

[00156] Still, the teachings of the present invention can also be applied not only to a medical professional in a hospital environment, but also to anyone who moves within that environment, such as visitors, companions, service providers, among others .

[00157] Also, the teachings of the present invention can be applied to more than a quarter of a hospital environment, for example, system 1 can be used to monitor hand hygiene practices in all areas of a hospital, and not just in a specific room. For example, and in a non-limiting way, the teachings of the present invention can be applied to monitor hygiene compliance in a surgical center in a given hospital.

[00158] Additionally and in addition to the sensors 2, 3, 4 and 5 covered in the present invention, the proposed system and method also allows the integration of other types of sensors not covered in the present invention. For example, a sensor can be used to monitor the opening and closing of doors in the hospital environment, thus determining when a particular person entered or left the environment.

[00159] Finally, and in addition to indicating the plurality of indicators

26, 27, 28 and 45 on the wearable device 15, a light signal can also be displayed on an indicating device 80 arranged close to the bed

Petition 870170025728, of 04/19/2017, p. 40/67

35/35 of the patient, where such a sign is an indication of the compliance of the hygiene protocols.

[00160] Additionally, the wearable device 15 can also provide, through the virtual environment 16, information to the medical professional about the patient as well as the environment in which he is disposed, such as: precautionary bed, patient pathology, type of procedure to be performed, and steps involved in the procedure to be performed.

[00161] Having described a preferred embodiment example, it should be understood that the scope of the present invention covers other possible variations, being limited only by the content of the appended claims, including the possible equivalents therein.
